The premise seems quite simple - a wealthy man with aspirations and a keen interest in the overlap between science and parapsychology seeks to make a name for himself with the mummified remains of an Egyptian Princess. With his valuable possession in tow, he heads for home in the US - aboard the RMS Titanic. What could go wrong when you're carrying the corpse of the unlucky princess on the maiden voyage of an unsinkable ship?
A short, punchy premise and adventure, filled with pages of clues, a timeline, general encounters and a six-pack of pregenerated characters. Good entertainment for a single evening, which you could expand out into something more substantial. Well worth hunting around online for some authentic handouts (boarding passes, perhaps) and deck plans of the ship, just to add some extra authenticity.
